This project page is on "GenBoarding" Akos Sovak's Peugeot car.
Engine highlights:
- 1998cc naturally aspirated (code: XU10J4)
- BOSCH MOTRONIC 1.3 DME originally
- 214cm3/min @3bar BOSCH 0-280-150-762 injectors (very likely high-Z)
- 60-2 wheel crank trigger
- no cam trigger
- narrow-band O2 sensor - has to go in favor of wideband
- TPS switch (tri-state --> upgrade to potentiometer)
- knock-sensor (would be fine to keep it functioning)
- flap-type AFM (has to go now)
- 2x2 wasted spark coils
- Individual throttle bodies (ITB)
- High duration cam (~280 degrees)
- CLT sensor data ? -> resistance values are rather same as in the Bosch '026' coolant termistor.
- IAC valve data : Bosch 2 pin version 0 280 140 516, pre-set spring at close position. (pwm freq unknown yet)
- Spring return type operating frequency is somewhat narrower than in double side(coil) valve type. Depends heavily from the spring natural frequency and moving mass. Is this sourced from Peugeot ? If so you could try to start controlling it by setting freq. to around 30-70 Hz.
In many aspects it's very similar to BMW engines (with Motronic 1.3), but due to the mods made to this engine there's a chance that it'll have erratic MAP and has to be an Alpha-n project. (Not sure however)
I'm not sure, but probably there are similar engines already:

- MembersPage/SeppoRepo ?
- MembersPage/JonasAndersson ?
- MembersPage/RichardWeller ?
Initial configs and other suggestions are welcome here!
